| 摘 要： | 根据系统的稳定性理论，设计了实现超混沌完全同步的状态观测器。利用混沌之间的同步，构建了实现保密通信的技术路线。信号经过加密并被混沌掩盖后，发射给接收端。采用4阶Runge—Kutta方法，对提出的保密通信系统进行了数值仿真。仿真结果显示，超混沌系统和其同步接收器之间在5S内已实现了完全同步，在信道内传递的加密信号中，原始信号完全被混沌所掩盖，仿真结果证实了设计方案的有效性。

| Abstract: | Based on the stabilization theory, a state observer is designed to realize a complete synchronization of four-scroll hyperchaotic systems. A technique of secure communication is proposed with chaotic synchronization. The encrypted signal is transmitted after being masked by a chaotic scheme. The proposed method is simulated using the fourth-order Runge-Kutta method. The results show that synchronization between the four-scroll hyperchaotic system and its state observer can be established in 5 seconds, and the encrypted signal is completely masked. The results show effectiveness of the method. |
